Effects of tadalafil to prevent injury on corpus cavernosum after vascular or nervous peri-prostatic bundle injury. Experimental model in rats

Abstract Purpose: To evaluate the effects of tadalafil (TD) in preventing histological alterations of the corpus cavernosum caused by isolated lesions of cavernous nerve (ILCN) and artery (ILCA) in rats. Methods: Fifty male Wistar rats were randomly assigned in five groups: G1: control; G2: bilateral ILCN; G3: bilateral ILCA; G4: ILCN+TD; G5: ILCA+TD. The cavernous bodies were submitted to histomorphometry, immunohistochemistry and biochemical analysis. Results: Nerve density was significantly higher in G2 and G4 compared to control (22.62±2.84 and 19.53±3.47 vs. 15.72±1.82; respectively, p<0.05). Smooth muscle density was significantly lower in G2 and G3 in comparison to G1 (12.87±1.90 and 18.93±1.51 vs. 21.78±1.81, respectively; p<0.05). A significant decrease in the sinusoidal lumen area was observed in G2 compared to controls (5.01±1.62 vs. 9.88±3.66, respectively; p<0.05) and the blood vessel density was increased in G2 and G3 (29.32±4.13 e 20.80±2.47 vs. 10.13±2.71, p<0.05). Collagen density was higher in G3 compared to G1 (93.76±15.81 vs. 64.59±19.25; p<0.05). Conclusions: Histomorphometric alterations caused by ILCN were more intense than those produced by vascular injury, but the collagen analyses showed more fibrosis in animals with ILCA. TD was effective in preventing the majority of the alterations induced by the periprostatic bundle injury.

Schooling impacts on the overactive bladder diagnosis in women

ABSTRACT Objective: To evaluate the overactive bladder (OAB) diagnosis using OAB-V8 and ICIQOAB questionnaires in women with different schooling and cultural levels. Materials and Methods: Three hundred and eighty six healthy women answered a clinical questionnaire filling out information about schooling, demographic and gynecological data. The OAB-V8 and ICIQ-OAB questionnaires were used to evaluate OAB diagnosis and symptoms; and the QS-F questionnaire, to determine the sexual function. All questionnaires were validated in Portuguese. Results: The mean age was 37.3 years-old. Regarding to schooling level, 23.1% had concluded primary education; 65.8%, secondary school; and 11.1% had higher education. Considering the OAB-V8 (score ≥8), 51.8% of evaluated women had OAB diagnosis. There was a positive linear correlation between the OAB-V8 and ICIQ-OAB questionnaires in its sections "a" (r=0.812, p<0.001) and "b" (r=759, p<0.001). There was a positive linear correlation between age and the amount of time used to answer the OAB-V8, ICIQ-OAB and QS-F questionnaires (p<0.001). The ICIQ-OAB was the hardest to answer for all schooling levels when compared to the other questionnaires. Women who had concluded primary and secondary education significantly demanded more help to answer all questionnaires than those with higher education (p<0.05). Furthermore, women with higher education took significantly less time answering all questionnaires when compared to their less educated counterparts (primary and secondary schooling), since they were quicker to answer each individual question. Conclusion: Educational level and ageing had an impact on women response using different questionnaires for OAB and sexual function evaluations.

Single-port retroperitoneal renal biopsy using standard urological instruments

Objective To describe the surgical technique and initial experience with a single-port retroperitoneal renal biopsy (SPRRB). Materials and Methods Between January and April 2013, five children underwent SPRRB in our hospital. A single 1.5 cm incision was performed under the 12th rib at mid-axillary line, and an 11 mm trocar was inserted. A nephroscope was used to identify the kidney and dissect the perirenal fat. After lower pole exposure, a laparoscopic biopsy forceps was introduced through the nephroscope working channel to collect a renal tissue sample. Results SPRRB was successfully performed in five children. The mean operative time was 32 minutes, and mean estimated blood loss was less than 10 mL. The hospital stay of all patients was two days because they were discharged in the second postoperative day, after remaining at strict bed rest for 24 hours after the procedure. The average number of glomeruli present in the specimen was 31. Conclusion SPRRB is a simple, safe and reliable alternative to open and videolaparoscopic approaches to surgical renal biopsy. .

Influence of clinical therapy and nutritional counseling on the recurrence of urolithiasis

PURPOSE: To evaluate the influence of combined clinical therapy and nutritional guidance on the recurrence of urolithiasis. METHODS: From our registry of patients with recurrent urolithiasis we selected 57 who had at least 5-years of follow-up. We collected 24h urine samples in order to analyze Ca, Na, uric acid, citrate, oxalate, and Mg concentrations and to assess urine volume. Patients filled out a clinical questionnaire before treatment, and abdominal radiographs and/or ultrasound were performed both before treatment and during the follow-up period. During follow-up, specific and individualized dietary advice was given based on the individual's metabolic disorders. Patients also received specific pharmacological treatment for their metabolic alterations. Outcome measures were metabolites in urine and the urolith recurrence rate. Pre- and post- intervention values were compared using tests as appropriate. RESULTS: Fifty six of the patients were male and the majority of patients were overweight. The mean BMI was 27 kg/m2. Urinary excretion of calcium, uric acid and sodium decreased significantly over the five year follow-up period. The number of uroliths that formed during the 5-year follow-up also decreased significantly compared to pre-treatment values. CONCLUSION: Individualized dietary advice combined with pharmacological treatment significantly reduces long-term urolithiasis recurrence. .

Comparative study between trimetazidine and ice slush hypothermia in protection against renal ischemia/reperfusion injury in a porcine model

PURPOSE: The aim of the study was to compare the effects of renal ice slush hypothermia and the use of trimetazidine in the protection against ischemia/reperfusion (I/R) injury. MATERIALS AND METHODS: Fifteen farm pigs were submitted to left kidney ischemia and right nephrectomy during the same procedure. Animals were divided into three groups. Group 1 was submitted to warm ischemia; Group 2 was submitted to cold ischemia with ice slush; and Group 3 received trimetazidine 20 mg one day and 4 hours before surgery. Ischemia time was 120 minutes in all three groups. Serum creatinine (SCr) and plasma iohexol clearance (CLioh) were measured before surgery and on postoperative days (PODs) 1,3,7, and 14. Semi-quantitative analyses of histological alterations were performed by a pathologist. A p value of < 0.05 was considered significant. RESULTS: All groups showed elevation of serum creatinine in the first week. Serum creatinine was higher in Group 3 in the first and third postoperative days (Mean Cr: 5.5 and 8.1 respectively). Group 2 showed a lower increase in creatinine and a lower decrease in iohexol clearance than the others. Renal function stabilized in the fourteenth POD in all three groups. Analyses of histological alterations did not reach statistical significance between groups. CONCLUSION: Trimetazidine did not show protection against renal I/R injury in comparison to warm ischemia or hypothermia in a porcine model submitted to 120 minutes of renal ischemia.

O objetivo deste relato é demonstrar os resultados da primeira cirurgia videolaparoscópica realizada no Brasil para o tratamento da doença oclusiva aorto-ilíaca, associada a procedimentos híbridos distais para lesões ateroscleróticas multissegmentares em paciente com isquemia crítica. A técnica videolaparoscópica é mais uma ferramenta minimamente invasiva, viável, segura e eficaz para o tratamento da doença oclusiva aorto-ilíaca extensa. A referida técnica, que nada mais é do que a cirurgia convencional realizada sob visão laparoscópica, tem bons resultados a longo prazo, associados à elegância técnica.

Laparoscopic surgery has been increasingly used as a less invasive surgical option for the treatment of aortoiliac occlusive atherosclerotic disease. The objective of this case report is to describe the results of the first laparoscopic surgery conducted in Brazil for the treatment of the aortoiliac occlusive disease associated with distal hybrid procedures to treat multisegmental atherosclerotic lesions in a patient with critical limb ischemia. The laparoscopic technique is an additional minimally invasive tool, being feasible, safe, and effective for the treatment of extensive aortoiliac occlusive disease. This technique, which is nothing more than a conventional surgery performed under laparoscopic viewing, brings good long-term results associated with technical elegance.

Prevalence and risk factors for urinary and fecal incontinence in brazilian women

Objective: To evaluate prevalence and risk factors of fecal and urinary incontinence (UI) in Brazilian women. Material and Methods: 685 women older than 20 years of age answered a questionnaire about urinary and fecal symptoms, clinical and obstetric antecedents. They were grouped according to presence or absence of UI. Results: Urinary and fecal incontinence was reported in 27 percent and 2 percent of cases, respectively. Mean age of incontinent women was significantly higher than continent ones. Incontinent women had a mean number of micturitions significantly higher than the continent ones. On average, incontinent women had higher rate of pregnancies and vaginal delivery when compared to the continent ones. Body mass index (BMI) was significantly higher in incontinent participants and in women with no UI complaints (27.35 vs. 24.95, p < 0.05). Fecal incontinence prevalence was 2 percent and occurred exclusively in patients with UI. Conclusions: Vaginal delivery and high BMI have been identified as risk factors for UI development while aging and number of pregnancies may be correlated factors.

Clinical and quality-of-life outcomes after autologous fascial sling and tension-free vaginal tape: a prospective randomized trial

Purpose: Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. Materials and Methods: Forty-one women were randomly distributed into two groups. Group G1 (n = 21), underwent AFS and group G2 (n = 20) TVT implant. The clinical follow up was performed at 1, 6, 12 and 36 months. Results: TVT operative time was significantly shorter than AFS. Cure rates were 71 percent at 1 month, 57 percent at 6 and 12 months in G1. In G2, cure rates were 75 percent at 1 month, 70 percent at 6 months and 65 percent at 12 months; there was no significant difference between groups. As regards the satisfaction rate, there was no statistical difference between groups. Analysis of quality of life at 36 months revealed that there was no significant difference between groups. Conclusion: Similar results between AFS and TVT, except for operative time were shorter in TVT.

Prevalência e implicações da incontinência urinária e fecal em mulheres / Prevalence and implications of urinary and fecal incontinence in women

Avaliar a prevalência da incontinência urinária (IU) e fecal em mulheres atendidas no ambulatório geral do Centro de Saúde Escola - Botucatu - SP. Foram escolhidas 807 mulheres aleatoriamente responderam um questionário aplicado por entrevistadores previamente selecionados e treinados, após assinarem termo de consentimento livre e esclarecido aprovado pelo CEP. Foram distribuídas em dois grupos: GI (n=567), mulheres sem perda de urina, e grupo G2 (n=240), com perda urinária. A média de idade no GI foi de 52 anos e no G2 de 51, não havendo diferença estatisticamente significativa entre os grupos. A prevalência de incontinência urinária foi de 29,7 porcento e em 59,2 porcento a urgência estava associada. O índice de massa corpórea (IMC) foi significativamente mais alto no grupo com perda de urina em relação às mulheres continentes. Na análise de outras variáveis não houve diferença estatisticamente significativa entre os grupos estudados. No grupo de mulheres incontinentes, observou-se número significativamente mais alto de partos vaginais nas mulheres com urgência e incontinência fecal em relação às continentes. A obesidade pode ser fator contributivo ou mesmo de piora da IU. A incontinência, seja urinária de urgência ou fecal, está relacionada a número mais alto de partos vaginais.

Our objective was to evaluate the prevalence of urinary incontinence in women seen at the general outpatient service of Health-School Unit of Botucatu - UNESP. 807 women answered a questionnaire applied by interviewers previously selected and trained, after signing a free informed consent approved by CEP. They were divided into 2 groups: GI (n=567) with women without urine loss and group G2 (n=240) with urine loss. Mean age in group GI was 52 years and 51 years in G2. There was no statistically significant diference between both groups. Urinary incontinence prevalence was 29.7 percent, and in 59.2 percent of cases urgency was associated. Body mass index (BMI) was significantly higher in the group with urine loss when compared to the continent women. By analyzing other variables there was no statistically significant difference between both groups. In the incontinent group, there was a significantly higher number of vaginal deliveries in women with urgency. Considering fecal loss, vaginal deliveries had a significantly higher number among incontinent than continent women. Obesity can either contribute of worsen urinary incontinence. Fecal or urge incontinence is related to the higher number of vaginal deliveries.

Retroperitoneoscopic renal biopsy in children

OBJECTIVE: We present our experience in a series of 17 consecutive pediatric patients submitted to retroperitoneal laparoscopic renal biopsy. MATERIALS AND METHODS: Retroperitoneal laparoscopic renal biopsy (LRB) was performed in 5 boys and 12 girls. Mean age was 8.1 years and age range from 2 to 12. Two or three trocars were used to expose the inferior pole of the kidney, remove enough cortical parenchymal specimen and fulgurate the biopsy site. Assessment included surgical time, estimated blood loss, hospitalization period, analgesia requirements, complications and number of glomeruli present in the specimen. RESULTS: LRB was successfully performed in all 15 patients (88 percent). In two cases, LRB was not possible to be performed. One patient was converted to a transperitoneal laparoscopy due to tear in the peritoneum. The other patient had had previous abdominal surgery and, during retroperitoneal balloon dilation, the peritoneum was opened and the open biopsy was performed. A third patient had postoperatively a perirenal hematoma, which was solved spontaneously. Complication rate was 17.6 percent (3/17 cases). Mean operative time was 65 minutes, while mean estimated blood loss was 52 mL, mean hospital stay was 2.2 days and mean analgesic requirement was 100 mg of tramadol. The mean number of glomeruli present in the specimen was 60. CONCLUSION: Retroperitoneal laparoscopic renal biopsy in children is a simple, safe. Bleeding is still the most common complication. However, direct vision usually allows a safe control of this drawback. In our institution, laparoscopic approach is the chosen procedure in pediatric patients older than one - year - old.

Urodinâmica convencional versus cistometria simplificada para caracterização da incontinência urinária feminina / Conventional urodynamics versus simplified cystometry for characterization of female urinary incontinence

Objetivo: avaliar a concordância dos diferentes parâmetros urodinâmicos comparados à cistometria simplificada, permitindo uma diminuição na relação custo-benefício no diagnóstico da incontinência urinária de esforço (IUE) na mulher. Métodos: foram coletadas e avaliadas retrospectivamente as informações contidas dos prontuários de trinta pacientes acompanhadas, no período de janeiro de 2000 a março de 2001. Todas foram submetidas a exame físico geral e ginecológico. O estudo urodinâmico foi realizado pela técnica convencional, utilizando-se aparelho Dynograph Recorder R-611. A cistometria simplificada foi realizada com auxílio de um equipo em "Y" de PVC (pressão venosa central), conectado a um sonda de Foley 14 F, que permitia tanto a infusão de soro fisiológico como a captação da pressão intra-vesical. Foram analisados os parâmetros: volume residual, capacidade vesical, complacência, presença de contrações involuntárias do detrusor e perdas urinárias aos esforços. Para determinação da proporção de concordância entre os métodos foram utilizados o teste de concordância de Pearson e o teste de Wilcoxon, para amostras relacionadas. Resultados: a média de idade foi de 50 anos, com extremos variando de 28 a 70 anos. O índice de concordância entre os estudos, na demonstração das perdas urinárias aos esforços, foi de 67 por cento. Para a detecção das contrações involuntárias do detrusor, a proporção de concordância foi de 90 por cento. A média do volume residual encontrado na cistometria simplificada foi de 16,8 ml contra 2 ml da urodinâmica convencional, com diferença significativa (p < 0, 01). A média de capacidade vesical máxima no estudo urodinâmico foi de 440,5 ml enquanto que, na cistometria simplificada, foi de 387 ml (p < 0,05). A complacência vesical foi, em média, significativamente maior na cistometria simplificada (43,0 ml/cmH2O) quando comparada ao estudo urodinâmico (31,5 ml/cmH2O), com p < 0,01. Conclusão: avaliações preliminares sugerem que a propedêutica uroginecológica associada à cistometria simplificada é uma opção a ser considerada na avaliação clínica e pré-operatória de pacientes com IVE em substituiçâo à urodinâmica convencional, particularmente onde esta última não se encontra disponível. A cistometria simplificada é um exame acessível que é capaz de detectar contrações involuntárias do detrusor, assim como identificar perdas urinárias com relativa sensibilidade, proporcionando ao examinador noções fidedignas do comportamento vesical.

Síndrome do desconforto respiratório agudo em UTI-Pediátrica / Acute respiratory distress syndrome in Pediatric Intensive Care Units

Apesar do avanço tecnológico empregado no tratamento de pacientes criticamente enfermos, a Síndrome do Desconforto Respiratório Agudo (SDRA) é condiçao clínica que se associa com elevadas taxas de mortalidade. Poucos sao os relatos do comportamento da SDRA em pacientes pediátricos. O presente estudo teve como objetivos examinar a incidência, a taxa de mortalidade, as doenças associadas e o curso clínico da SDRA em crianças, com atençao especial para a avaliaçao dos índices de trocas gasosas e sua correlaçao com a mortalidade. No período de janeiro de 1990 a julho de 1994 foram admitidos 1.155 pacientes na UTI-Pediátrica, sendo que destes 12 (1 por cento) preencheram os critérios diagnósticos de SDRA e foram submetidos a protocolo preestabelecido. Da análise dos protocolos dos pacientes obtiveram-se os seguintes resultados; 1) Os principais eventos predisponentes foram a sepsis e a pneumonia, presentes em 58 por cento e 33 por cento dos casos, respectivamente; 2) 75 por cento das crianças tinham menos que um ano de idade; 3) Durante a ventilaçao mecânica verificou-se que: em metade dos casos a FiO2 manteve-se em valores iguais a 100 por cento, a Pip máxima atingiu 40 cm H2O em 75 por cento dos pacientes e a Peep 12-15 cm H2O em 70 por cento; 4) A relaçao PaO2/FiO2 era menor que 100, à admissao, em 75 por cento dos casos e dos nove pacientes nos quais esta relaçao manteve-se menor que 100, após 48 horas, oito (75 por cento) evoluíram para óbito; 5) Todos os pacientes apresentaram disfunçao de no mínimo dois órgaos e sistemas, sendo que destes 50 por cento apresentaram disfunçao de quatro ou mais órgaos; 6) A taxa de mortalidade foi de 75 por cento. Pela dramática evoluçao dos pacientes com SDRA, contínuos esforços devem ser implantados para aumentar o conhecimento desta doença em nosso meio.
